To all whom it may concern:

Be it known that l, LUTHER E. Gneonsiz'rn, a citizen of the United States, residinpr at Duluth, in the eounty of Saint VLouis and State of Minnesota, have invented certain new and useful Improvements in Cheek Writer-s,y of which the followingr is a aperitieat ion.

The subject of this` invention is a rheek writer`r and the main obje-xl vonteinplated h v the invention is the provision of :i rheoh writer whit-h will write a complete eheeh.

.\nother ohjeet within the eonteinplation of the invention is the provieion ot means vfor mounting type to he shifted into rows for printing upon the eheek.

A still further object of the invention is the provision of means for shifting the type.

A further object within the contemplation olE the invention the provision of means for resetting the machine when a rheek has heen written.

Another' object is the provision of for lorkirngr certain of the type or type to repeat.

A still further object of the invei'ition is the provision of a simple, durable, and etli nient rheek writer.

lVith the foregoing and other objects; in view which will appear as the desuriptiou proreeds, the invention resides' in the novel arrangement and construction of parts means a ll the forth in the description and claimed in the rlaims. it being` understood that rhanges in the structural arrangement and eolnhiiiation ot parts may he made within the spirit of the invention.

A practical embodiment of the invention shown in the accompanying' drawings., u herein Figure l. is a plan view of a` eher'k writer l-onstrluted in aeeordanee with the inven tion;

Referring to the drawings hy numerals of referen ee The operative parts of the device are housed in a suitable easing l havingr a. top plate or key-hoard 2 which key-boardas provided with longitudinally extending slots arranged in transverse rows. (lf these slots, the upper row 3 is positioned toward the right hand side of the machine and buttons 3 are slidalole therein forA the purpose of shifting type to print the date on a check, as Will be hereinafter described. The buttons 3 may he most ronveniently made as illustrated in Figs. 9 and lll, with a T hlqel( 3 provided with a threaded stud adapted to screw into a. recess in the knurled button portion and with a shank 3' formed `for threaded engagement with the T blockY The second row ol' slots 4 are spaced longi tiulinally from the. slots 3 and buttons 4 are slidable in these Slots for the purpose of shifting type to print the payees naine upon a Cheek. There are also in this row, and at the right hand end thereof, slots 3 Yin which slide buttons Sl for the purpose of shifting type to print, in numerals, the amount of the cheek.

A. third row of slots ."3 is spared longitir dinally from the seeond row and buttons 5 are slidahlo in theae slots for the purpose of 4lifting type to print in the written amount of the eheek.

The rear plate (l of the easing is niovahle slightly inwardly, by means hereinafter deserilied, for the purpose of permitting` the ssttype to protrude through the plate when lhe type is to he inked and the ehm-k brought against the type for the purposil of produrA ing an impression thereon. Iu order that lla' l'vpe may protrude platt` i? and he `brought piu-rh. Vous olA slots li' of tlu,l rear plate.

iu rontui't with the extend lrausveisely through thi` rear Within the casing is laced a suitable sup porting frame in the si e bars 7 of which are secured horizontal] y disposed, transversely 'arranged shafts 8. l'Mounted on each of these shafts and extending rearwardly therefrom is a series of type supporting bars 9 the forward ends of which are bifurcated for ashort distance longitudinally, and these ends are apertured transversely to receive the shafts 8. Also mounted on these shafts and rotatable thereon within the bifurcated forward end of each type bar 9 is a chain Wheel 10, herein shown as a sprocket wheel.

Passing about each wheel 1() and-resting 0n its type bar 9'is a chain 11, some of the links of which, indicated at 11 are type. As will be seen most clearly in Fig. 3, these bars are so arranged that by rotating the Wheels the chains will be moved rectilinearly. longitudinally of the bars and the type arranged in rows extending horizontally and spaced vertically apart.

For the purpose of moving the chains about the wheels and along the type ba rs 9. angularly formed arms 13 extend down Wardly and rearwardly from each button and havev their rearmost ends pivotally secured to the chains 11 so that, by sliding a button along its slot the chain may be moved to bring any type desired in position at the rear end of the type bar 9 and before the proper slot 6.

-That the buttons may be moved to positions to bring the proper type into position to print, characters are arranged beside each slot in the key board and, in'order that a button maybe brought to rest and retained at a position corresponding to a selected character, ratchet bars 14 are arranged longitudinally of the supporting frame and beside the slots, and the attenuated ends of these bars are pivotally secured in supportN ing bars 15 which extend transversely of the frame and are positioned to underlie the s ace between the ends of the rows ofr slots.

pawl 16 is secured to the depending neck of each button and is adapted to contact its ratchet bar to permit the button to be moved toward the rear end of the machine but to normally prevent its return toward the,

front end of the machine. As will be understood, the teeth of the ratchet bars are so spaced as to hold the buttons at each character marked upon the key board which characters are so arranged as to bring the corresponding type to the ends of the type bars and in position before the slots 6.

After the type has been moved into posi tion as just set forth. the check is )laced on the plate or platen 17` the lower e ge of which is hingedly connected to the lower edge of the rear plate 6, and a lever 18, which rises from one end of a horizontally sposed rock bar 19, which bar is journaled within the' casing 1 at the rear end and near the bottom thereof, and which lever extends above the key-board 2, passing through a slot formed 1n the keydioard1 is grasped and thrown toward the front of the machine to bringr the platen in contact with the type and print the check.

To swing the platen about its hinge, arcuaic links or bars 2() are connected to the platen near each end thereof and extend through slots l'ornieiLin the rear plate G having their other ends connected, the one to the lever 1H. and the other to an arm 21 which rises from the other end of the rock bar 19.

When the platen 17 is swung to contact the type, it also becomes necessary to move the back plate (i inwardly that the type may protrude through the slots 6' Aand be in-position to be Inet by the platen. For this purpose a rock shaft Z2 extends transversely of the machine adjacent the back plate and has its ends journaled in the side plates of the casing. Fast on this shaft are the cam plates 23. one adjacent the lever 'IFE and the othcr adjacent the arm 2l. Each plate i5 provided with a cani groove into which projects thc angled cnil of :i bar 24 which is secured to and projects inwardiy from the rear plate (i. Each cam plate is also formed with au upstanding yoke 25 which normally straddles a wiper arm 2G extending from the lever 18 and the arm 21, re spectively. Upon initial movement of the lever 18 and arm Q1, the wiper arms 26 throw thc cams to remove the cam faces 25 from contact with the rear plate 6 and, through the cam groove and rods 24. draw the plate inwardly.

An 'ink pad '25) may be supplied on the back plate (i and a carriage bearing ink rollers 3U may travel in slots 31 formed in said rear plate. This carriage may be reciprocated in any of the usual and well known ways but, as the same forms no part of the present invention, specific means for operating the carriage have not been shown but the same may he operated by hand.

After the check has been printed it bccoines necessary to return the type and the buttons to their normal positions. To accomplish this coil springs 32 are provided in each wheel 10 and one end of cach spring r is* shaft, and each linger contacts the under face ol a ratchet bar and is adapted to rock the ratehet bar and lift its serrated edge when the rock shaft is rocked in one dii-eetion. llilien the ratchet har is rocked npwardly it is disengaged from the pawl lo which immediate@Y springe beneath the rati-liet liar under tile aetion of the spring 35. its` movement being limited by the atop iti formed on the pan'l. The springs 3d are now l'ree to aet and draw the type and tinte tone to normal position. As the ratchet hars stop short ot' the positions of rest of the out` tous, the hare `fravitate to normal position when the paws have passed from under them and are again in position to Contact the pawls when the buttons are onee more moved. y

To rock the roek shafts 33 a eranl arm 3C extends from eaeh rock shaft and is eonneeted hy a link llT to a crank 255 which is eupported on the frame near the rear end of the niaehine. llaeh crank 38 is in position to he strut-k bl* a eam lug' at] which extends laterali)Y from the arm 2l. When the arm 2t is swung* to normal position the eain lup,r engages the ends ot the rranhn 3H and swings them toward the rear plate t3, thus, through links -57 and rranlie 36, rocking the hatte 33. Upon swinging the arm 2l in the oppoeito direi-tion. the rounded oli' ende ot' the erauliS 23H are engaged liv the eurved eam face of the lng 4l and are moved .ao siigrlitly as to have no operative etieot upon the shafts 33.

'l'o provide repeat meehanism, arms -ttl tend radially from eaeh rock shaft 33, at diametrieall'vV oppoeite position near one end thereof. and are in position to he strnel liv plantaire -tzj earried in blot-.lie it?, whieli are leerured to the top plate .2 and whieh pluneew projeet downwardly through aperturen` formed in the plate. 'l'he plungere are retained in normal poeition and ont ol' ron-- lar'l with the arma lli liv coiled springe '11 n'hieli surround tlieplnmfers and are ronlined lietween the upper fares ol' the liloeli's il. and lnittonl EL attarhed to the upper ends ol the plunger-s.
